  • The Magellanic System's Interactive Formations
    Publ. Astron. Soc. Aust., 2000, 17, 1–5. The Magellanic System’s Interactive Formations M. E. Putman Research School of Astronomy & Astrophysics, Australian National University, Private Bag, Weston Creek PO, ACT 2611, Australia [email protected] Received 1999 November 17, accepted 2000 January 7 Abstract: The interaction between the Galaxy and the Magellanic Clouds has resulted in several high-velocity complexes which are connected to the Clouds. The complexes are known as the Magellanic Bridge, an HI connection between the Large and Small Magellanic Clouds, the Magellanic Stream, a 10 100 HI lament which trails the Clouds, and the Leading Arm, a diuse HI lament which leads the Clouds. The mechanism responsible for these features formation remains under some debate, with the lack of detailed HI observations being one of the limiting factors in resolving the issue. Here I present several large mosaics of HI Parkes All-Sky Survey (HIPASS) data which show the full extent of the three Magellanic complexes at almost twice the resolution of previous observations. These interactive features are connected, but unique in their spatial and velocity distribution. The dierences may shed light on their origin and present environment. Dense clumps of HI along the sightline to the Sculptor Group, which may or may not be associated with the Magellanic complexes, are also discussed.

  • Report: Inquiry Into the Current State of Australia's Space Science
    Chapter 3 Looking out 3.1 Australia has built a strong reputation for the work of its astronomers in 'looking out' (or 'listening out') to the distant universe and tracking and communicating with space objects closer to Earth. This aspect of space is predominantly the domain of scientists, with few commercial applications. 3.2 The range of activities, and the enthusiasm for them, was demonstrated to the committee by a CSIRO scientist: The looking-up lens is about expanding the frontiers of science. One of those areas is the radio astronomy area…where we are asking some of those fundamental questions: what is the origin of magnetism; are Einstein’s laws fully correct; and where is the dark matter coming from? Some of these are going to have the next Nobel prizes in them, and that is fantastic.1 Astronomy "Jupiter and Saturn, Oberon, Miranda and Titania.

Maggini, I-64100 Teramo, Italy Received .....; accepted ..... ABSTRACT We revise the scenario of the formation of Galactic globular clusters (GCs) by adding the observed detailed chemical composition of their different stellar generations to the set of their global parameters. We exploit the unprecedented set of homogeneous abundances of more than 1200 red giants in 19 clusters, as well as additional data from literature, to give a new definition of bona fide globular clusters, as the stellar aggregates showing the presence of the Na-O anticorrelation. We propose a classification of GCs according to their kinematics and location in the Galaxy in three populations: disk/bulge, inner halo, and outer halo. We find that the luminosity function of globular clusters is fairly independent of their population, suggesting that it is imprinted by the formation mechanism, and only marginally affected by the ensuing evolution. We show that a large fraction of the primordial population should have been lost by the proto-GCs.

  • Interstellar Media in the Magellanic Clouds and Other Local Group Dwarf Galaxies
    Interstellar Media in the Magellanic Clouds and other Local Group Dwarf Galaxies Eva K. Grebel1 1Max-Planck-Institut f¨ur Astronomie, K¨onigstuhl 17, D-69117 Heidelberg, Germany Abstract. I review the properties of the interstellar medium in the Magellanic Clouds and Local Group dwarf galaxies. The more massive, star-forming galaxies show a complex, multi-phase ISM full of shells and holes ranging from very cold phases (a few 10 K) to extremely hot gas (> 106 K). In environments with high UV radiation fields the formation of molecular gas is suppressed, while in dwarfs with low UV fields molecular gas can form at lower than typical Galactic column densities. There is evidence of ongoing interactions, gas accretion, and stripping of gas in the Local Group dwarfs. Some dwarf galaxies appear to be in various stages of transition from gas-rich to gas-poor systems. No ISM was found in the least massive dwarfs. 1 Introduction There are currently 36 known and probable galaxy members of the Local Group within a zero-velocity surface of 1.2 Mpc. Except for the three spiral galaxies M31, Milky Way, and M33, the irregular Large Magellanic Cloud, and the small elliptical galaxy M32 all other galaxies in the Local Group are dwarf galaxies with MV > −18 mag. In this review I will concentrate on the properties of the interstellar medium (ISM) of the Magellanic Clouds and the Local Group dwarf galaxies, moving from gas-rich to gas-poor objects. Recent results from telescopes, instruments, and surveys such as NANTEN, ATCA, HIPASS, JCMT, ISO, ROSAT, FUSE, ORFEUS, STIS, Keck, and the VLT are significantly advancing our knowledge of the ISM in nearby dwarfs and provide an unprecedented, multi-wavelength view of its different phases.

    BOOK LAUNCH: 2 DECEMBER 2013 Minister, Joy Burch, Vice‐Chancellor, Ian Young, Director, Matthew Colles, Ladies and Gentlemen. The idea of writing this book came from Harvey Butcher. About two years ago he phoned me to come over and have a chat with him. After drinking lots of coffee and talking about the universe and all that, he asked me with his charming smile, will you write a book on Mount Stromlo Observatory for Canberra’s centenary celebrations. That is how this book came to be written by Harvey, Ralph and me. In fact, Ralph began the book. The book is about a group of astronomers and their wonderful telescopes. Albert Einstein Mount Stromlo Observatory is a remarkable institution. It is all the more remarkable because in 1905 two things took place which had an important bearing on this institution. In that year, an unknown clerk in the patent office in Switzerland by the name of Albert Einstein published his Theory of Special Relativity which questioned the very foundations of Newtonian physics. 12 years later he published his Theory of General Relativity and introduced a fudge factor called the Cosmological Constant to stop the universe from expanding as this was the conservative view in astronomical circles. The universe was supposed to be static according to Newton. It is rather amazing that a revolutionary had become a conservative in so short a time. About 80 years later Brian Schmidt, at Mount Stromlo Observatory, tackled the Cosmological Constant and won the Nobel prize for his work on the accelerating universe. It was a conceptual shift in our thinking verry similar to that introduced by Copernicus in the 16th century.

A main goal of YMCA and STEP is to identify candidate stellar clusters and complete their census out to the outermost regions of the Magellanic Clouds. We adopted a specific over-density search technique coupled with a visual inspection of the color magnitude diagrams (CMDs) to select the best candidates and estimate their ages. To date, we analysed a region of 23 sq. deg. in the outskirts of the Large Magellanic Cloud, detecting 85 candidate cluster candidates, 16 of which have estimated ages falling in the so called “age gap".

  • Discovery of O Stars in the Tidal Magellanic Bridge: Stellar
    Astronomy & Astrophysics manuscript no. main ©ESO 2020 November 17, 2020 Discovery of O stars in the tidal Magellanic Bridge Stellar parameters, abundances, and feedback of the nearest metal-poor massive stars and their implication for the Magellanic System ecology Varsha Ramachandran, L. M. Oskinova, and W.-R. Hamann Institut für Physik und Astronomie, Universität Potsdam, Karl-Liebknecht-Str. 24/25, D-14476 Potsdam, Germany e-mail: [email protected] Received <date> / Accepted <date> ABSTRACT The Magellanic Bridge stretching between the Small and the Large Magellanic Cloud (SMC and LMC), is the nearest tidally stripped intergalactic environment. The Bridge has a significantly low average metallicity of Z . 0:1Z . Here we report the first discovery of O-type stars in the Magellanic Bridge. Three massive O stars were identified thanks to the archival spectra obtained by the ESO’s Very Large Telescope FLAMES instrument. We analyze the spectra of each star using the advanced non-LTE stellar atmosphere model PoWR, which provides the physical parameters, ionizing photon fluxes, and surface abundances. The ages of the newly discovered O stars suggest that star formation in the Bridge is ongoing. Furthermore, the discovery of O stars in the Bridge implies that tidally stripped galactic tails containing low density but highly dynamical gas are capable of producing massive O stars. The multi-epoch spectra indicate that all three O stars are binaries. Despite their spatial proximity to each other, these O stars are chemically distinct. One of them is a fast-rotating giant with nearly LMC-like abundances. The other two are main-sequence stars that rotate extremely slowly and are strongly metal depleted.
